小编Joa*_*son的帖子

此代码适用于Windows窗体:

string URI = "http://localhost/1/index.php?dsa=232323";
string myParameters = "";

using (WebClient wc = new WebClient())
{
    wc.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";
    string HtmlResult = wc.UploadString(URI, myParameters);
}

但我想从Windows Phone 8发送http GET请求.在wp 8中没有方法UploadString()等等......

我有一个包含此列表的表单:

<tr>
  <td>State/Province:   </td>
  <td colspan="3">
     <select style="width:200px" name="state"> 
       <option value="All">All</option>
       <?php for( $i=0;$i<sizeof($states);$i++) { ?>
         <option value=<?php echo($states[$i][0]) ;?>>
           <?php echo( $states[$i][0]) ;?>
         </option> 
       <?php }?>
     </select>
  </td>
</tr>

我的问题是state当选择由两个或多个单词组成时的价值.例如,如果我有"纽约"这个词:只存储"新"这个词$_POST['state'].

• 这个错误的原因是什么？
• 如何将所有值存储在我的变量中$_POST['state']？

在python中,返回第n个斐波纳契数的Fibonacci序列的递归函数可写为:

def fib(n):
    if n == 1:
        return 0
    if n == 2:
        return 1
    return fib(n-2) + fib(n-1)

我理解这个函数是如何工作的,但如果有人以前从未见过这个函数,那么如何得到它呢？

谢谢

我写的时候:

SELECT deptno,ename, RANK () OVER (PARTITION BY deptno ORDER BY sal DESC) rank 
FROM emp

我得到sal和deptno排序的结果集,但为什么呢？我没有在主要指定它ORDER BY？

我试图使用一个字符串并将其转换为int来比较第一个第一列和所有行中输入的字符串中的所有数字.当我输入一个数字时,我得到一个NullPointerException.问题是,当我觉得我已经正确地声明了所有对象时,我不明白为什么编译器会告诉我这个.请帮忙!

import java.util.ArrayList;

public class Decoder
{

    private int[][] zipdecoder;
    private ArrayList<Integer> zipcode;
    private String finalCode;
    private String bars;
    private int place;
public Decoder()
{
   int[][] zipdecoder = new int[][]{
       {1,0,0,0,1,1},
       {2,0,0,1,0,1},
       {3,0,0,1,1,1},
       {4,0,1,0,0,0},

       {0,1,1,0,0,0}
       };
    zipcode = new ArrayList<Integer>();
}

public void insertToArray(String zip)
{
    int count = 0;

    for(int i = 1; i<zip.length()+1;i++)
    {
        String piece = zip.substring(count, i);

        int number = Integer.parseInt(piece);
        for(int j = 0;j<10;j++)
        {
            if(number == zipdecoder[j][0]){
            for(int a …

我正在为变量分配一个函数,如下所示:

def hello(name):
    print "Hello %r \n" % name

king = hello
print "%r, King of Geeks" % king("Arthur")

它在终端返回:

你好'
Arthur'None,极客之王

是什么赋予了？

我有最长的联合案例陈述我曾经做过,我无法解决这个错误.IT说它附近的语法错误,我完全不好意思,我无法弄清楚这样一个简单的错误

SUM(CASE 
      WHEN COL_V_STD_REP_FullCourseDetail.SYSTEM = 'GEMS' 
      THEN CASE 
             WHEN RRDD LIKE '12%' OR RRDD LIKE '13%' OR RRDD LIKE '16%' OR 
                  RRDD LIKE '17%' OR RRDD LIKE '2706%' OR RRDD LIKE '2707%' OR 
                  RRDD LIKE '2331%' 
             THEN [DUR_IN_Hours]

for(int i =0; i<8;i++){
  for(int j =0; j<8;j++){
    Ratsuk.getNewtablero().getMesa(i,j).setBackground(matrizcolor[i][j]);
    if (Ratsuk.getNewtablero().getMesa(i,j).getBackground()==Color.lightGray);
    Ratsuk.getNewtablero().getMesa(i,j).setEnabled(false);
  }
}

Ratsuk.getNewtablero().getMesa(i,j) 用于调用newtablero内部的JButton 2d数组,matrizcolor是相同大小的2d颜色数组.

当它运行时,该阵列中的所有按钮不仅禁用浅灰色的按钮.任何1可以解释我为什么？

            current =r.Next(1,7);
                noa += 1;
                Console.WriteLine(current + " has been rolled.");
        }
